I bought Hider 2 a year ago of so and have used it periodically. I have had no problems using it on a Seagate portable drive. Having that added layer of security on a drive that I might lose or that might be compromised while on the move was the primary motivation for trying Hider. The software has met all my expectations. It is eaasy and quick to transfer files to and it is as easy to unhide them when needed. I haven’t put the program through any torture tests, but using it periodically for all types of files I have had zero problems. The negative reviews below from earlier this year seem vague and lacking in any detail that would allow me to evaluate their credibility. I have used the software cautiously but find it to works exactly as advertised.
